The U.S. Department of Homeland Security (DHS) and the Department of Justice both released interim guidance documents this month to implement the Cybersecurity Information Sharing Act of 2015 (CISA). The bill requires both agencies to establish a voluntary information sharing process to encourage sharing of cyberthreat information between the government and the private sector.

The documents address the requirements for sharing information with the DHS National Cybersecurity and Communications Integration Center, which shares information among public and private sector partners to build awareness of vulnerabilities, incidents, and mitigations.

Cyber and industrial control systems users can subscribe to information products, feeds, and services at no cost.
